[texts]Spacetime Geometry and General Relativity - Neil Lambert
The plan of the course is as follows. We will first review Special Relativity. It is assumed that you have a reasonable knowledge of this as well as tensors such as those encountered in Electromagnetism. We will review (or perhaps introduce) covariant index notation and spacetime. Next we will discuss Einstein's famous thought experiment and follow his logic that leads to the notion that, in the presence of gravity, spacetime is curved...

[texts]The quantum gravity lagrangian - Nigel B. Cook
A previous paper ( http://vixra.org/abs/1111.0111 ) makes some calculations from a quantum gravity theory and sketches a framework for further predictions. This paper defends in detail the lagrangian for quantum gravity, based on the theory in our earlier paper, by examining the simple physical dynamics behind general relativity and gauge theory.

[texts]Rank-2 tensor compression of Maxwell's equations does not turn them into rank-2 spacetime curvature - Nigel B. Cook
Maxwell's equations of electromagnetism describe three dimensional electric and magnetic field line divergence and curl (rank 1 tensors, or vector calculus), but were compressed by Einstein by including those rank-1 equations as components of rank 2 tensors. However, Einstein did not express the electromagnetic force in terms of a rank-2 spacetime curvature. In order to unify or even compare the equations for two forces (gravity and electromagnetism), you need first to have them expressed in ter...

[texts]Colliding Plane Waves in General Relativity- Chapter 21 - Related Results - Jerry Griffiths
It is �nally appropriate to review a series of results which are related to the analysis of exact solutions describing the collision of plane waves in a �at background, which is the main subject of this book. The results described in this chapter di_er from those given in previous chapters in a variety of ways. A number of interesting results have been obtained using di_erent approaches, by considering the background in region I tobe non-�at, or by considering alternative gravitational the...

[texts]Colliding Plane Waves in General Relativity- Chapter 14 - The Initial Value Problem - Jerry Griffiths
The approach to �nding exact solutions that has been taken so far has involved initially solving the �eld equations in the interaction region IV and then investigating the conditions under which these solutions can be considered as the result of collisions of plane waves. In this way, resulting solutions are found �rst and the initial conditions are obtained subsequently. In this chapter it is appropriate to return to the original problem of specifying the initial data and then attempting ...

[texts]Colliding Plane Waves in General Relativity- Chapter 20 - Other Sources - Jerry Griffiths
So far only solutions of the Einstein or Einstein-Maxwell equations have been considered. This has enabled the properties of colliding plane waves to be considered in the various cases in which the approaching waves were gravitational waves, pure electromagnetic waves, or combinations of both. A number of similar results have also been obtained for a variety of other sources. These will be reviewed in this chapter.

[texts]Colliding Plane Waves in General Relativity- Chapter 15 - Colliding Electromagnetic Waves- The Bell-Szekeres Solution - Jerry Griffiths
In an important paper, Bell and Szekeres (1974) gave an exact solution which describes the collision and subsequent interaction of two electromagnetic plane waves. This solution, which appears to be remarkably simple, will be described in this chapter. Other exact solutions describing colliding electromagnetic waves will be described in Chapters 16 and 17, after more powerful techniques have been developed.

[texts]Colliding Plane Waves in General Relativity- Chapter 11 - Ernst's Equation for Colliding Gravitational Waves - Jerry Griffiths
In this chapter we will present an analysis of the colliding wave problem using a method that has become familiar in the study of stationary axisymmetric space-times. In this case the �eld is described in terms of a complex potential function that is referred to as the Ernst potential (see Ernst 1968a). This approach leads directly to various methods for generating further exact solutions.

[texts]Colliding Plane Waves in General Relativity - Collated Notes - Jerry Griffiths
In this book we will be considering one of the most obvious situations in which the e_ects of the non-linearity of Einstein�s equations will be manifest. We will be considering the interaction between two waves. By restricting our attention to somewhat idealized situations, it will be possible to describe some types of wave interaction in terms of exact solutions. Moreover, these solutions have a clear physical interpretation in terms of combinations of gravitational or electromagnetic waves a...

It is not the purpose of this chapter to introduce or explain Einstein�s general theory of relativity, since the reader who is not already familiar with it is unlikely to gain much from this book. The main purpose here is simply to clarify the notation that will be used. It is also appropriate in this chapter to brie�y introduce the Newman�Penrose formalism which facilitates the geometrical analysis of the colliding plane wave problem and which will be used in Chapter 6 to derive the �el...

The solutions of Khan and Penrose (1971) and of Szekeres (1970, 1972), discussed in Chapters 3 (and Section 8.2) and 9, describe the collision of plane gravitational waves with aligned linear polarization. It is convenient to consider separately in this chapter a number of other exact solutions that satisfy this same condition.

One of the �rst exact solutions of Einstein�s equations describing the mutual scattering of gravitational waves was that of Khan and Penrose (1971). This describes the collision and subsequent interaction of two plane impulsive gravitational waves and their subsequent interaction. Following this pioneering work, many more exact solutions have been obtained. However, the general character of almost all solutions that have subsequently been found is basically the same as that of the original s...

The colliding plane wave problem has been formulated in the previous chapters as a characteristic initial value problem with initial data speci�ed on two null hypersurfaces. At this point it is necessary to discuss the junction conditions between the four regions described in Figure 3.1, and particularly on the initial boundaries of region IV.

The purpose of this chapter is to consider in more detail some of the geometrical properties of space-times that contain plane waves. Part of the discussion here follows naturally from that at the end of the previous chapter. Here, some more general results of a geometrical nature will be considered, and an intuitive approach to the collision of plane waves will also be developed.

[texts]5. Explaining The Theory.full
The paper entitled “The theory of everything and the big bang” attempts to explain the most mind bending realisation of all time known as “Unification”. Unification of all the forces, every law of physics in to one single-mathequation. This paper gives us a brief idea about how our universe works and also about the ideas that revolutionized the physics world- “General Relativity” and “Quantum physics” along with the new striking idea called “The String Theory.”

[texts]Link between Allais effect and General Relativity’s residual Arc during solar Eclipse - Russell Bagdoo
The purpose of this article is to establish a relation between two gravitational anomalies, the Allais effect that occurs during solar eclipse and the General Relativityâs residual arc of the curvature of light during the same eclipse. There is a systematically observed deflection about 10 percent larger than the theoretical value of General Relativity which coincides with the âeclipse effectâ found by Maurice Allais.

The atmosphere and ocean are continuously stratified due to change in temperature, composition and pressure. These changes in the ocean and atmosphere can lead to significant variations of density of the fluid in the vertical direction. As an example, fresh water from rivers can rest on top of sea water, and due to the small diffusivity, the density contrast remains for a long time. The density stratification allows oscillation of the fluid to happen...

To describe a problem in mathematical terms, one must make use of the basic laws that govern the elements of the problem. In continuum mechanics, these are the conservation laws for mass and momentum. In addition, empirical constitutive laws are often needed to relate certain unknown variables; examples are equations of state, Hooke�s law between stress and strain, etc. To derive the conservation law one may consider an in�nitesimal element (a line segment, area or volume element), yielding ...
